Why the Distinction Matters

It is entirely possible for an economy to grow rapidly while development lags behind. Consider a hypothetical country where a mining or oil sector expands very fast, pushing up national output substantially, but the profits are concentrated among a small number of firms and owners, and the jobs created are few relative to the size of the population. In such a case GDP growth looks strong on paper, yet most citizens may see little change in their access to clean water, schooling, or healthcare. This is why economists insist on tracking development indicators separately from growth indicators — growth is a necessary condition for development in the long run (an economy cannot sustainably improve living standards without producing more), but it is not a sufficient condition on its own.

The opposite pattern can also occur: an economy can achieve meaningful gains in health and education outcomes even at a relatively modest rate of income growth, if public policy deliberately directs resources towards schooling, sanitation and healthcare. Kerala's historical experience of achieving high literacy and life-expectancy figures at levels of income growth lower than many other Indian states is frequently cited as an example of development outcomes advancing somewhat independently of pure income growth, precisely because of sustained public investment in social sectors. The general lesson is that development is what growth is ultimately supposed to deliver, but delivering it requires deliberate distributional and social-sector effort, not growth by itself.
